AKo leads 58.79% to 41.21% before the flop, counted exactly over every board, with the split by flop type and suit. Before any board card is dealt, AKo holds 58.79% equity against 87s, which leaves 87s with 41.21%. ## AKo against 87s: the numbers **Exact preflop results for AKo against 87s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | AKo | 58.580 | 0.418 | 41.002 | 58.789 | | 87s | 41.002 | 0.418 | 58.580 | 41.211 | Here an offsuit hand (AKo) meets a suited hand (87s). Neither hand shares a rank with the other, so this is a contest of high cards, connection and suits. AKo is ahead, but 87s is far from dead: it takes 410 of every 1,000 deals outright. Of every 100 boards, about 0.42 are split pots, and the equity figures already include them. Among the 169 starting hands, AKo is number 12 and 87s is number 100 by strength against a random hand. **Boards behind the percentages: 82,190,592 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | AKo | 48,147,000 | 344,000 | 33,700,000 | | 87s | 33,700,000 | 344,000 | 48,147,000 | The board total is exact, 48 deals at 1,712,304 boards each.

For the 48 ways to deal one AKo and one 87s without reusing a card, grouped by suit pattern, every one of the 1,712,304 possible boards is dealt and both seven-card hands are compared. A tie counts as half a win in the equity column, and each board is counted once under each of its ten three-card flops. Source: our own exact count from the GeorgeLiPoker poker math library.
